**Definitions:**

**Kilonewton** (abbreviation: **kN**): is the International System of Units (SI) derived unit of force where 1 kN = 1000 N. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion.

**Atomic Mass Unit** (abbreviations: **amu, or u**): also known as dalton (symbol: Da), is a standard unit of mass that used on an atomic or molecular scale (atomic mass). One unified atomic mass unit is about the mass of one nucleon (either a single proton or neutron) and equivalent to 1 g/mol.

## How to Convert Kilonewton to Atomic Mass Units

*Example: How many atomic mass units are equivalent to 29.29 kilonewton?*

As;

1 kilonewton = 6.1427793270495E+28 atomic mass units

29.29 kilonewton = Y atomic mass units

Assuming Y is the answer, and by criss-cross principle;

Y equals 29.29 times 6.1427793270495E+28 over 1

(i.e.) Y = 29.29 * 6.1427793270495E+28 / 1 = 1.7992200648928E+30 atomic mass units

Answer is: 1.7992200648928E+30 atomic mass units are equivalent to 29.29 kilonewton.
